Loading... Please wait...The Fishpond Yellowstone is a lot of bag for the price. It is a large bag at 25" x 15" 19" and a volume of over 6,500 cubic inches and, with its large, wide-open zipper design, allows you to really load it up for a long trip. The Yellowstone is made of tough 16 oz. cotton canvas with a durable, abrasion-resistant bottom. The bottom compartment is ventilated and also zips open super wide for storage of wet waders, boots and other wet gear. A padded changing mat folds out to assist in changing in and out of waders. Other features are three big exterior pockets, a fully lined interior on the upper compartment, and a nice, padded shoulder strap.
